The first partial derivatives of the function f(x, y) = x^4 - 6xy^5 are ∂f/∂x = 4x^3 - 6y^5 and ∂f/∂y = -30xy^4.
The first partial derivatives of the function f(x, y) = x^4 - 6xy^5 with respect to x and y can be found as follows.
The partial derivative with respect to x (denoted as ∂f/∂x) can be obtained by treating y as a constant and differentiating the function with respect to x. In this case, the derivative of x^4 with respect to x is 4x^3. The derivative of -6xy^5 with respect to x is -6y^5, as the constant -6y^5 does not depend on x. Therefore, the first partial derivative of f(x, y) with respect to x is ∂f/∂x = 4x^3 - 6y^5.
Similarly, the partial derivative with respect to y (denoted as ∂f/∂y) can be found by treating x as a constant and differentiating the function with respect to y. The derivative of -6xy^5 with respect to y is -30xy^4, as the constant -6x does not depend on y. Thus, the first partial derivative of f(x, y) with respect to y is ∂f/∂y = -30xy^4.
In summary, the first partial derivatives of the function f(x, y) = x^4 - 6xy^5 are ∂f/∂x = 4x^3 - 6y^5 and ∂f/∂y = -30xy^4. These derivatives represent the rates at which the function changes with respect to each variable individually.

If A and B are mutually exclusive, then P(A\capB) = 0.
A and B are independent if and only if P(A\capB) = P(A)P(B)
If A and B are two events with P(A) = 0.4, P(B) = 0.2, and P(A B) = 0.5. Find the following:
(a) P(A\capB) (b) P(A?\capB) (c) P(A?\cupB?) (d) P(A|B)
If A and B are independent events with P(A) = 0.4 and P(B) = 0.2. Find the following:
Roll a die once. The event of getting a "2" and the event of getting a "5" are (a) independent;
(b) mutually exclusive;
(c) Neither
Roll a die twice. The event of getting a "2" on the first roll and the event of getting a "5" on the second roll are
(a) independent;
(b) mutually exclusive;
(c) Neither
The probability of both events occurring is P(A ∩ B) = P(A)P(B) = 0.16^2 = 0.0256.
The event of getting a "2" and the event of getting a "5" on the first roll of a die are mutually exclusive events because they cannot both occur in the same trial. The probability of either of these events occurring is P(A) = 0.16, and the probability of both events occurring at the same time is P(A ∩ B) = 0.00.
The event of getting a "2" on the first roll and the event of getting a "5" on the second roll of a die are independent events. This can be confirmed using the formula P(A ∩ B) = P(A)P(B). The probability of getting a "2" on the first roll is P(A) = 0.16 and the probability of getting a "5" on the second roll is P(B) = 0.16. Thus, the probability of both events occurring is P(A ∩ B) = P(A)P(B) = 0.16^2 = 0.0256.

Element X on Planet Qatar has three known isotopes: X-121 with a relative abundance of 43.2%, X-123 with a relative abundance of 53.1%, and X-129 with a relative abundance of 3.70%. What is the average atomic mass in amu of Element X given this information?
QUESTION 2.
How did Rutherford's experiment change the way scientists had previously viewed atomic structure? How did this pave the way for subsequent changes up to and including the currently accepted quantum mechanical atomic model?
QUESTION 3.
How is percent abundance related to average atomic mass?
a) The percentage abundance Shows us the amount of the substance in the element
b) The relative atomic mass for the element X has been obtained as 122.5 amu
c) The Rutherford's model explained showed the movement of the electrons.
What is the isotope?The isotopes of an elements are the atoms of the elements that have the same atomic number but do not have the same mass number. We know that the atoms of the isotopes of the element that we have are important as we try to determine the relative atomic mass of the element as we have the element X in this case.
Now we have that;
Relative atomic mass = Weighted average of all the isotopes
As such we have;
(121 * 0.432) + (123 * 0.531) + (129 * 0.0370)
52.27 + 65.31 + 4.773

What is the additive inverse of 2 /- 7?
The additive inverse of 2 /- 7 is -2 /+ 7.
An additive inverse is a number that when added to the number in question, the sum is equal to zero. This can be expressed by the formula x + (-x) = 0, where x is the number in question. In this case, x is 2 /- 7. So, when 2 /- 7 is added to its additive inverse, -2 /+ 7, the sum is 0. This can be expressed mathematically as 2 /- 7 + (-2 /+ 7) = 0. Calculating this equation, we get 2 /- 7 + (-2 /+ 7) = -2 /+ 7 + (-2 /+ 7) = -4 /+ 14 = 0. Therefore, the additive inverse of 2 /- 7 is -2 /+ 7.

Create two different explicit equations that describe the values in the table. Use a different point in the table for each of the equations you create. Choose one of the equations you created to produce an equivalent form that reveals the y intercept of the function within the equation.
Answer:
Step-by-step explanation:
if x were starting at 0, we would have
y = (x - 7)×7 = 7x - 49
but we start at x = 57. We need adjust for these extra 57 to get the above equation.
so, it
y = (x - 57 - 7)×7 = (x - 64)×7 = 7x - 448
so, for
y = (x - 64)×7
I choose x = 57
y = (57 - 64)×6 = -7×7 = -49
for
y = 7x - 448
I choose x = 58
y = 7×58 - 448 = 406 - 448 = -42
from this form we get the y-intercept (the y- value when x = 0) : -448

The following is a basic formula to find the scale factor of a dilated figure is: : Scale factor = Dimension of the new shape ÷ Dimension of the original shape.
What's the scale factor of the dilation?Sizing Factor (Dilation) The image's size will depend on the scale factor, which is used to dilate a mathematical entity (compared to the original object). An expansion happens when the scaling factor's absolute value exceeds one.
What is Dilation Geometry?Dilation is the process of increasing an object's size without altering its shape. Depending on the scale factor, the object's size may increase or shrink. A square of side 5 units can be widened to a square of side 15 units using dilation math, but the square's shape doesn't change.
In geometry, dilation math is used to enlarge and reduce two- or three-dimensional figures.
The Scale FactorA scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is the ratio of the original figure's and dilated figure's sizes.
You can use r or k to represent the scaling factor.
If the scale factor is more than 1 (k > 1), the image is expanded.
If the scale factor is less than 1 (0 k 1), the image is condensed.
If the scale factor is 1 (k = 1), the image doesn't change.
It should be noted that the scale factor's magnitude is taken into account and that it cannot be 0.
Scale Factor FormulaAn object's size can change depending on the scale factor, either growing or shrinking. The following is a basic formula to determine a dilated figure's scale factor:
Scale factor = Dimension of the new shape ÷ Dimension of the original shape.Another approach to express this formula that aids in determining the new shape's dimensions is as follows:

What is the graph of a function?
The graph of a function is a visual representation of the relationship between the input values (x-coordinates) and the output values (y-coordinates) of the function. In other words, it is a visual representation of the function's rule.
The graph of a function can take many different forms, depending on the function's rule. Linear functions, for example, will produce a straight line on the graph.
i) 2y - 4x < 8 can be solved by adding 4x to both sides and then dividing by 2, giving:
y < 2x + 4.
ii) -4y > -x + 12 can be solved by adding x to both sides and then dividing by -4, giving: y < x/4 - 3.
iii) | x + 3 | = y, you can split this into two cases:
i. x + 3 = y
ii. -(x + 3) = y
iv) |2x – 6| + 2 = y, you can split this into two cases:
i. 2x - 6 + 2 = y
ii. -(2x - 6) + 2 = y
We can use these equations to plot the graph on a coordinate plane.
Hence, the solution is the set of all points (x,y) that satisfy the inequalities:
y < 2x + 4, y < x/4 - 3, x + 3 = y, and 2x - 6 + 2 = y.
